'@The track 'xture @261s readi-lygandeconomically I,rn-,ade 1 from flat plate metal I which isv forgedpr yotl-lerwise; formed with :a substantially horizontal Lil fcross beameengag-ingportion A2-8, .a substantially vertical rai] web engaging portion 30, and an intermediate angularportion 32 angledto overlie the nclnediipperfsurtaceof the rail. base. The welding ofthe .tension memberlto the track fixture is greatly facilitated by providing the fixture with a cup-shaped, upwardly extending upset portion or dome 34, which is apertured, as indicated at 36, to receive the tension member. The dome may be formed by any convenient means, as for instance a bulldozer. Thus, as illustrated best in Fig. 5, the dome 34 provides a considerable space on its underside into which a portion of the tension member I8 projects so that it may readily be welded, as indicated at 38, to the fixture. T'he construction is such that neither the tension member nor the welding extends beyond the plane .of the under side of the intermediate angular portion 32 of the fixture.

The vertically disposed rail web engaging portion 3i) is provided with a pair of spaced apart apertures 40, by means of which it may be bolted to the rail. The outer surface of the xture may be cut away immediately underneath the apertures 4D, as indicated at 42, to provide the necessary clearances for the securing means.

One of the advantages of the above-described track fixture resides in the fact that the tension cross beam 24 may be welded directly to the horizontal portion 28 of the xture, thereby eliminating any blocks or the like as required in prior art structures. Another advantage of the track fixture, which results from the fact that the base plate is generally triangular in shape, is that a saving in material is effected and the welding. of

the horizontal portion to the cross beam facilitated.

The right compression track fixture 22 comprises a base plate 44 cut and formed like the tension track fixture, with a substantially horizontal portion 46. a vertically disposed portion 48, and an intermediate angular portion i). The base plate has welded to it at right angles to the axis of the compression member a compression member abutment plate 52. Additional rigidity is given to the abutment plate and fixture as a whole by means of a generally triangular brace 54 welded to both the base and abutment plates.

The vertically disposed portion 48 is apertured, as indicated by reference character 56, and the outer surface is cut away, as indicated by reference character 58, for the reception of the bolts and securing nuts. I'he left compression fixture is symmetrical to the one described, except for the angular location of the abutment plate which must of necessity be different because of the fact that, as explained above in connection with the tension joint, the bumper head is supported slightly olf center.

The described construction of the compression track fixture to which the compression member is weldedto form a unitary whole is very simple and rugged. It, too, is so constructed that the compression cross beam may very easily be welded to the horizontally disposed portions 46.

From the above-described detailed description, it may be seen that the present invention provides a considerably simplied bumping post and that the invention likewise comprehends features which may be applied to various types of bumping bumping posts wherein the cross beams are not utilized. v

What I claim as new and desireto secure by United States Letters Patent is, as follows:

1. In a bumping post, a track xture compris-f ing a generally triangular plate member apertured to receive a stress transmitting member, said plate member being provided with an upset portion surrounding the aperture to provide space on the lower side of said plate member for Welding the end of said stress transmitting member to said plate member.

A bumping post, including in combination, a bumper head, compression members diverging rearwardly, `downwardly and outwardly from said bumper head, tension members diverging forwardly, downwardly and outwardly from said bumper head, track xtures for said tension members comprising vertical portions adapted to be secured to the webs of the rails, inclined portions adapted to overlie the inclined surfaces of the bases of the rails, said inclined portions being apertured and upset to provide dome-likev portions surrounding the apertures through which the tension members project and to provide spaces for welding the ends of the tension members to the fixtures, and compression track x-tures comprising similarly formed portions, compression member abutment plates welded to said xtures and to said compression members at right angles to the axes of the latter, and braces welded to said abutment plates and fixtures on the sides oppositethe compression members.

9. A bumping post, including in combination, a bumper head, compression members divergng rearwardly, downwardly and outwardly from said bumper head, tension members `diverging forwardly, downwardly and outwardly from said bumper head to opposite pointsV on a railway track, tension and compression cross beams located below the track, track xtures for said tension members comprising Vertical portions adapted to be `secured to the webs of the rails, inclined portions adapted to overlie the inclined surfaces of the bases of the rails, and horizontal portions secured directly to said tension cross beam, said inclined portions being apertured and upset to provide dome-like portions surrounding the apertures through which the tension members project and to provide spaces for welding the ends of the tension members to the respective fixtures, and compression track Xtures comprising similarly formed portions of which the verticall and horizontal portions are secured, respectively, to the webs of the rails and to said compression cross beam, compression member abutment plates welded to said xtin'es and to said compression members at right angles to the axes of the lat-ter, and braces welded to said abutment and base plates on the sides opposite the compression members.
